使用aws sdk执行s3 putObject api时出错

Question

我正在使用php AWS开发工具包，将对象上传到s3，我将存储桶策略设置如下：

            {
                "Version": "2012-10-17",
                "Statement": [
                    {
                        "Sid": "AddPerm",
                        "Effect": "Allow",
                        "Principal": "*",
                        "Action": "s3:GetObject",
                        "Resource": "arn:aws:s3:::bucketname/*"
                    },
                    {
                        "Sid": "Stmt1488493308547",
                        "Effect": "Allow",
                        "Principal": {
                            "AWS": "IAMuserARN"
                        },
                        "Action": "s3:*",
                        "Resource": [
                        "arn:aws:s3:::bucketname",
                        "arn:aws:s3:::bucketname/*"
                        ]
                    }
                ]
            }

，并将IAM用户策略设置为具有s3的完全访问权限。 但是当我对putObject运行代码时，出现以下异常：

在“ https://s3.me-south-1.amazonaws.com/bucketname/uploads/media/media_36_file.png”上执行“ PutObject”时出错； AWS HTTP错误：客户端错误：PUT https://s3.me-south-1.amazonaws.com/bucketname/uploads/media/media_36_file.png导致了403 Forbidden响应：AccessDeniedAccess DeniedF78430（被截断了...）AccessDenied（客户端）：Access Denied-AccessDeniedAccess DeniedF784301719C49C953fPX0U28ONnHQuUvJKJGQ3VBUfELBqmxy2> 7
